can I install a GOG game (moto racer 2) on 2 computer? (both are mine)..
The GOG game's are DRM free, right?
is there a restriction on this?

THANK YOU!!

Only one legal restriction. You must own all of the computers you install that game on.
If the other computer is one of another member of the household, no one would kill you, but it would be fair if they purchase theire own copy of the game :)

Oh yeah, I meant as long as you own the computers, I have just realized how horribly structured that sentence was :D

Games are DRM-free. You may install them on as many machines as you want, and be totally fine with this morally and legally.

Fixed that for you.

Haven't the GOGs themselves stated that they are cool with sharing games along your household?

The licence doesn't cover this obviously, but I remeber some blue text about this.

Anyway, the only thing restricting you, when it comes to GOG games, is your own morality.

From http://www.gog.com/en/support/website_help/downloads_and_games :

9. Can I install one game both on my laptop and desktop PC at home?
Yes. We do not limit the number of installations or reinstallations, as long as you install your purchased games on PCs in your household. So yeah, if you've got a render-farm in the basement, you might actually break the world record for the number of legal Fallout installations in one household. However, if you think about installing your game on a friend's PC or sharing it with others then please don't do it, okay?

Thanks to ALL, don't worry, the 2 PC's are mine.
So no problems,
thank you GOG for great game! :)
